Behavior of talc and mica in copper ore flotation ...
Talc is a naturally hydrophobic mineral, and therefore it is easily floatable. There have been many studies to overcome this problem, and depress talc with various reagents. In this study the flotation of a copper ore in the presence of talc and muscovite was studied. It was found that talc can affect copper flotation mainly via froth phase.

The flotation and adsorption of a new polysaccharide konjac gum (KG) on pyrite and talc in the presence of pre-adsorbed potassium butyl xanthate (PBX) is investigated. The micro-flotation results show that KG is a quality depressant for talc and that conditioning the minerals initially with PBX before KG will increase the recovery difference between pyrite and talc.
Froth Flotation Principles
Talc Flotation. The mineral talc is found associated with several varieties of gangue material and the flotation process is the efficient and accepted means for production of talc concentrates. In these flotation separations it frequently happens that gangue rejection is a valuable by-product.
Study on Wetting Behavior and Flotation Separation of Talc ...
Molybdenite and talc were selected as research object in paper and crystal structure, interaction between H2O molecule and minerals surfaces, surface wettability, flotation behavior were studied by density functional theory method and flotation experiments. The results showed that molybdenite and talc were layered minerals which exhibited similar surface wettability.
SURFACE CHEMISTRY OF TALC FLOTATION - McGill University
Talc is formed when silica tetrahedra condense with brucite. Talc differs from the majority of sheet silicates in that its silicon oxygen sheets are electrically balanced. The bonding between the sheets of tal~ molecules results from weak residual oxygen-oxygen bonds. Talc is …
Selective flotation separation of molybdenite and talc by ...
This trend is consistent with the results of flotation, showing that the treatment by HA increased the wettability of molybdenite much more than talc, and inhibited bubble attachment on molybdenite surfaces, lowering the recovery of molybdenite while not affecting the flotation of talc. 3.3.

These analyses represented impurity rejections of 77, 85, and 65 pct respectively. Weight recovery for this open circuit was 52 pct; however, weight recovery was estimated to be 75 pct with cleaner tailings recycle. Results from this investigation show that column flotation is a viable means for beneficiating talc.
